Perhaps you should try some spelling variations:
"modified graph convolutional algorithms" » "modified graph convolution algorithms", "modified graph evolution algorithm", "modified graph evolutionary algorithm", "modified deep convolutional algorithms", "modified trained convolutional algorithms"
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified graph convolutional algorithms") or ("modified adaptive quantization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified graph convolutional algorithms") OR ("modified adaptive quantization algorithm")).
• Removing quotes may allow a broader search: (( modified graph convolutional algorithms ) or ( modified adaptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified graph convolutional algorithms") or ("modified adaptive quantization algorithm"))*.
